This topic describes how to change the cell protocol information,
define custom properties for the cell, and add additional nodes.
Before you begin
Before you can configure
cells, you must install the WebSphere® Application Server, Network Deployment product.
About this task
When you create a deployment manager profile, a cell is
created. A cell provides a way to group one or more nodes of your WebSphere Application Server, Network Deployment product. You
define the nodes that make up a cell, according to the specific criteria
that make sense in your organizational environment. You probably
do not need to configure the cell again.
Administrative configuration
data is stored in XML files. A cell retains master configuration
files for each server in every node in the cell. Each node and server
also have their own local configuration files. Changes to a local
node or to a server configuration file are temporary, if the server
belongs to the cell. While in effect, local changes override cell
configurations. Changes to the master server and master node configuration
files made at the cell level replace any temporary changes made at
the node when the cell configuration documents are synchronized to
the nodes. Synchronization occurs at designated events, such as when
a server starts.
To view information about and to manage a
cell, use the settings
page for a cell.
Procedure
- Access the settings
page for a cell. Click System Administration > Cell from
the navigation tree of the administrative console.
-
If the protocol that the cell uses to retrieve information
from a network is not appropriate for your system, select the appropriate
protocol. By default, a cell uses Transmission Control Protocol (TCP).
If you want the cell to use User Datagram Protocol, select UDP from
the list for Cell discovery protocol on the settings page
for the cell. It is unlikely that you need to change the cell protocol
configuration from TCP.
- Click Custom Properties and
define any name-value
pairs that your deployment manager needs.
- Click New.
- Specify a name and value for the custom property.
- When you install the WebSphere Application Server, Network Deployment product, a
node may have been added to the cell. You can add additional nodes
on the Node page.
Click Nodes to access the Node page, which you use to manage nodes.
Both Internet Protocol
Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are now supported
by WebSphere Application Server, but there
are restrictions that apply to using both IPv4 and IPv6 in the same
cell. Note that when you add a node to a cell, the format in which
you specify the host name is based on the version of IP the node will
be using. For further information, read the topic on IP version considerations
for cells.
Results
Depending on which steps
you performed, you changed the cell
protocol information, defined custom properties for the cell, and
added additional nodes.
What to do next
You can continue to administer
your WebSphere Application Server, Network Deployment product
by doing
such tasks as managing nodes, node agents, and node groups.
